SHOE-LACE TIP. I

I Application filed my" 17,

T 0 all whom it may concern:

Be it-known that. I, HENRY G. PETERSEN, a citizen of the United States,and resident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements inShoe-Lace Tips; and I do hereby declare that the following is a full,clear, and exact description thereof.

This invention relates to shoe lace tips.

Shoe lace tips are usually formedof metal and, as is wellknown, thistype, due to the extreme thinness of the metal, has two seri' ousdrawbacks. One of these drawbacks or defects is that the metal itselfhas not sufficient spring or rigidity to grip the lace securely, and theother drawback is that no adequate means are provided for reinforcingthe tip against lateral bending.

This invention is designed to overcome the above noted defects, andobjects of the invention are, therefore, to provide a metal tip for ashoe lace which will grip the lace securely without tearing it, andwhich is reinforced and strengthened against lateral bending.

Further objects are to provide a gripping device for shoe lace tipswhich is itself reinforced against bending or distortion and which willsecurely hold the lace in its correct position relatively to the tip.

Further objects are to provide a shoe lace tip which is of sturdy andsimple design, which may be cheaply manufactured, and which will notopen up when in use.

An embodiment of the invention is shown in the accompanying drawings, inwhich:

Figure 1 is a view of the shoe lace tip applied to the lace, with partsbroken away to show the interior construction.

Figures 2, 3 and 4 are enlarged views taken on section lines 22, 33 and4:4 of Figure 1.

Figure 5 is a sectional view taken on the line 55 of Figure 4. r

Figure 6 is the view of the blank in its extended condition.

The shoe lace tip is formed from a blank whose body portion 1 is ofsubstantially rectangular contour, and is provided witha marginalportion 2 adapted to be folded at right angles to the adjacent portionof the rolled tip along the dotted Figure 6.

This blank is further provided with saw tooth projections 4 which, asmay be'seen line 3 of 1923. Serial No. 639,668.

from Figure 6, are provided with marginal portions 5. These marginalportions, in the finished tip, are folded along the curved dotted lines6 of Figure 6. I

Prior to the rolling operation, the material is depressed, as indicatedin-dotted lines in Figure 6, to form the depressed rein forcing portions7 of the finished tip.

The blank is further provided with a lip 8 which, as may be seen fromFigures 4 and 5, is adapted to be folded'over theadjacent portions ofthe rolled blank at'itsrear end to prevent unrolling. Itis, of course,to be understood that-a lip of similar construction may be providedadjacent the front end.

In forming the tip the portions 5 are folded under, as indicated indotted lines in Figure 1, and as shown in full lines in Figures Qand 4,to form a reinforced sub- 7 stantially right angle edge for the forwardedge of the teeth. This provides a rounded edge in place of theotherwise sharp edge, and prevents cutting and tearing of the lace whenthese edges are forced therein. The marginal portion 2 extends radiallyinwardly to form a longitudinally extending reinforce to guard againstlateral bendingof the tip. The body portionis folded around the shoelace 9 and the tongue 8 is folded inwardly to bind the adjacent portionblank together, as may be seen from Figures 4 and 5, to preventunrolling. It is well known that this unrolling most frequently occursat the rear end of the tip adjacent the lace and, consequently, a lip atthis point is extremely serviceable although a lip at the forward end ofthe tip may also be provided.

It will be seen that teeth have been provided for engaging thelace andthat these teeth have rounded forward edges and are corrugated or dishedso as to add to their strength.

It will further be seen that although extremely thin metal may beemployed in forming these tips, that this metal is so without anytendency of the laces sliding therefrom which would occur with a taperedforward edge. This right angle front portion is backed by a relativelylong tapered rear portion to provide adequate strength.

Although one form of the invention has been described in considerabledetail, it is to be understood that the invention may take various formsand is, therefore, to be limited only as claimed.

I claim:

1. A shoe lace tip comprising a tubular body portion and inwardlydirected reinforced teeth.

2. A shoe lace tip comprising a tubular body portion, and inwardlydirected teeth adapted to project into the lace, said teeth being dishedto provide stiffness to resist distortion.

3. A shoe lace tip comprising a tubular body portion and inwardlydirected teeth having folded front edges.

4. A shoe lace tip comprising a sheet metal tubular body portion, teethextending inwardly thereof, and a longitudinally extending reinforcingrib joining successive teeth and extending outwardly from the outermostof said teeth.

5. A shoe lace tip comprising a rolled metal tubular body portion havingradially extending internal teeth, said teeth having a graduallytapering rear edge and a folded front edge extending transversely of theaxis of said tip, and a reinforcing rib projecting radially inwardly ofsaid tip, said reinforcing rib being of lesser width than said teeth.

6. A shoe lace tip comprising a rolled metal tubular body portion havingsubstantially radially extending internal teeth projecting from one edgethereof, said teeth having a tapering rear edge and having a foldedfront edge, said teeth being dished transversely of the axis of said tipwhereby increased strength is afforded said teeth against distortion.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee, in the county of Milwaukee and State of Wisconsin.

HENRY G. PETERSEN.
